This is the factory sub I pulled from my wife's 2011 Honda Pilot. It is very odd looking. It looks like a siamese twin that was never separated at birth. The 2 cones are different sized. The one playing to the front is 7.25" and the one behind is 6". As far as the sound.....not very good. The voice coil is front mounted (i.e. illusion audio) on the rear 6" "sub".
So, is this isobaric or one 6" sub with a 7" passive radiator attached?
Interesting design and I'm just wondering if the benefit to this design may cause us to see more. People that have more knowledge, please discuss.
